CLOSI J'RE MOUNTING AND OPERATING MEANS.

Application filed January 28, 1926. Serial No. 84,430.

The invention relates broadly to operating and mounting means forclosures which areslidable Within frames, and the specific applicationof the invention herein disclosed, is in connection with sliding sashesof a window. One object of the invention is to provide new and improvedmeans for sliding the closure and applying uniform force to oppositeedges thereof during the sliding operation, sothat no binding willoccur.

Another aim is to so relate certain parts as to permit the closure to beswung laterally from its normal plane whenever desired, and in thisconnection, a further aim is to provide unique guiding means for theclosure when in its normal plane.

A still further object is to provide a simple and inexpensive, yet anefficient and durable, hand-operated unit forming part of theclosure-operating means.

With the foregoing in view, the invention resides in the unique subjectmatter hereinafter described and claimed, for carrying out the objectsof the invention.

Figure 1 of the accompanying drawings, is a side elevation partlybroken, away and in section, showing the upper and lower sashes of awindow equipped with the invention.

Figure 2 is an edge View partly broken away and in section.

Figure 3 is a horizontal sectional view on an enlarged scale, asindicated by line 3-3 of Fig. 1.

Figure 4 is a detail horizontal section on the planes indicated bylines4-4: of Figs. 2 and 6.

Figure 5 is an enlarged vertical sectional. view as indicated by line 5'-5 of Fig, 6.

Figure 6 is a vertical sectional view on line 6-6 of Fig. 3.

Figure 7 is a perspective view showing the relation of gears and racksfor sliding the sashes.

Figure 8 is a sectionalperspective of 'a portion of the frame showingthe manner in which the gears project into grooves thereof for mesh withthe racks of the sashes.

The construction herein disclosed may be considered as the preferredform of the invention, with the understanding however that within thescope of such invention as clalmed, numerous modlfications maybe made.

F designates a window frame in which upper and lower, slidable sashes Uand L are disposed. The mounting and operating means for both sashes isthe same and a specific description of such means is only line,preferably comprising two cable portions 11 and a chain portion 12,'saidcable portions being suitably connected with a hinge member 13 whichpasses slidably through a vertical slot 14 in a side member of the frameF, said hinge member havingan inner leaf 15 suitably secured to the sashL, while the outer end of this member which passes through the slot 14,is preferably provided with a guide 16 engaging the frame. The edgeportion of the sash L, contiguous to the'hinge member 13, is'providedwith a longitudinal. rib 17 normally received in a longitudinal groove18 formed in the coacting side member of the frame, the formation of therib and groove being preferably that disclosed in Fig. 3. Obviously,when the rib and groove are interengaged, the sash may freely slide, butsaid rib leaves said groove when the sash is swung inwardly upon thehinge, for instance, to clean the window pane or panes.

The chain portion 12 of the flexible line, is disposed at the side ofthe frame remote from the hinge member 13. said chain por tion. meshingwith the teeth of a sprocket or gear 19. A portion of thissprocket' orgear passes through a slot 20 into a groove 21 in the adjacent sidemember of the frame and meshes withthe teeth of a rack bar 22 which isretractably connected with the sash L and projects slidably into saidgroove thus be seen that this member acts upon the rack bar 22 to exerta sliding force on a one edge of the sash L, and at the same time, saidmember drives the flexible line 11-12, so that the latter pulls upon thehinge member 13 at the opposite edge of the sash. Thus, uniform force isexerted at opposite edges of the sash to readily slide the latter andinsure that no canting or binding shall take place.

In connecting the rack bar 22 with the sash L, I form said rack bar withupper and lower transverse slots 23 and pass bolts 24 through said slotsand the sash. said bolts having thumb nuts 25 which normally clamp therack bar frictionally against the sash. When these nuts are releasedhowever, the bar 22 may be inwardly slid from the groove 21, permittinginward swinging of the sash upon the hinges above described. Tofacilitate retraction and projection of the bar '22, itis preferablyformed with a finger groove 26.

Quite a novel arrangement is provided for mounting and driving themember 19. This member is carried by a short horizontal shaft 30 whichis rotatably mounted in a pair of lower lugs 31 projecting from avertical plate 32 which is secured by screws or the like 33 to the frameF. The plate 32 is also provided with an upper lug 3a and with anintermediate lug 35 between its upper and lower lugs, The lug 34rotatably supports an operating shaft 36 whose outer end is of suitableform to be engaged by a hand crank (not shown). This shaft is providedwith a bevel gear 37 meshing with a bevel pinion 38 on a vertical shaft39 which is rotatably supported by the upper lug 34 and the intermediatelug 35, the lower end of this shaft 39 being provided with a worm 40between the lugs 31, which worm meshes with a worm gear 41 carried bythe shaft 30. It will thus be seen that rotation of the shaft 36 bymeans of a hand crank or the like, will drive the shaft 39 and the worm40, causing the latter and the worm 4 1 to rotate the shaft 30 and themember 19. for the purpose of adjusting the sash. lVloreover, as theworm and worm gear will remain in any position at which they may bestopped, no other locking means are necessary and it will be obviousthat the use of sash balances is likewise unnecessary.

Preferably, the lugs 31 are spanned by a short metal strip 42 carrying aguard 43 which prevents accidental disengagement of the chain portion 12from the member '19, this detail being shown most clearly in Figs. 2 and4;.

It will be seen from the foregoing that simple and inexpensive, yetefiicient and reliable means have been provided for carrying out theobjects of the invention, and while. the details disclosed arepreferable, modifications may be made as above set forth.

I claim 1. In an operating means for a closure slidable within a frame;cable guides mounted at the four corners of the frame, a flexible linetrained around said guides, said line having a chain portion at one sideof said frame, means connecting said line to the closure at the otherside of the frame. a sprocket mounted at said one side of the frame andmeshing at one side of its axis with said chain portion of the line, arack bar meshing with said sprocket at the other side of its axis andconnected to the closure, and means for driving said sprocket.

2. In an operating and mounting means for a closure slidable within aframe; a gear mounted at the exterior of one side member of the frameand projecting through a slot in said side member to expose its teeth atthe interior of the frame, a rack bar retractably connected to theclosure and meshing with said exposed teeth of the gear, and a hingeslidably engaged with a. slot in the opposite side member of the frameand directly connected with the closure.

In an operating and mounting means for a frame-contained closure. a gearmounted at the exterior of one side member ofthe frame and projectingthrough a slot in the latter, the inner side of said side member havinga longitudinal groove into which the teeth of said gear project, a rackbar projecting edgewise from the closure into said groove and meshingwith said teeth of said gear, and means mounting said rack bar on saidclosure for retraction from said groove.

4. In a closure operating means; a plate for attachment to a frame, anupper lug and a lower pair of laterally spaced lugs projecting from oneside of said plate, an intermediate lug projectingfrom the plate betweenthe upper and lower lugs, a shaft rotatably supported by the upper andintermediate lugs and having a worm between the lower lugs, aclosure-operating shaft rotatably supported by the lower lugs and havingaworm gear in mesh with said worm a readily rotatable shaft supported bythe upper lug, and gearing connecting said readily rotatable shaft withthe first named shaft,

5. In an operating means for a closure slidable and swingable within aframe, cable guides mounted at the four corners of the frame, a flexibleline trained around said guides, means connecting said line to one sideof the closure, operating means engageable with said line at theopposite side of the closure and retractable means attached to saidopposite side of the closure for holding the latter against swingingmovement, said retractable means being engageable with said operatingmeans for raising and lowering the closure.

6. In an operating means for a closure slidably and swingably mountedwithin a frame, hinges connected to one side of the closure and having aslidable engagement with the adjacent side of the frame, cable guidesmounted at the four corners of the frame, a flexible line trained aroundsaid guides and having its ends connected with said hinges, operatingmeans engageable with said line at the sides of the closure 0 posite toits hinged side, means retractablg connected with the closure andengageable with said operating means for raising and lowering theclosure, said retractable means being adapted to hold the closureagainst swinging movement. 10
